Using both individual and dyadic creativity tasks, Studies 1 and 2 provided initial demonstrations that time spe...

The larger societies within the IUPS family hold meetings that are attended by scientists from many countries. This is not restricted to the US and UK societies. I recently lectured to the a...

We give a graph theoretical proof for the existence of a walk connecting left and right sides of a rectangle when it is partitioned into (finitely many) rectangles colored in a specific way, and the walk is aloud to use only borders between rectangles of different color. The problem was originally introduced by J.R. Isbell in the proof of his Zig-Zag Theorem. We prove the existence of such a wa...

More and more embedded devices store sensitive information that is protected by means of cryptography. The confidentiality of this data is threatened by information leakage via side channels like the power consumption or the electromagnetic radiation. In this paper, we show that the side-channel leakage in the power consumption is not limited to the power-supply lines and that any input/output ...
